Abstract：
OBJECTIVE: Previous research on obesity surgery (OS) showed that patients do not only experience weight loss but also improvements in certain mental health outcomes (e.g., depression) after OS. However, self-harm behaviors might increase after OS. Regarding self-harm, the literature is mostly limited to studies using data from hospital or emergency room charts. This longitudinal study examined self-reported self-harm behaviors and potential psychopathological correlates before and after OS.
METHODS: Pre-surgery patients (N = 220) filled out a set of questionnaires before and approximately six months after OS. Self-harm behaviors were captured with the Self-Harm Inventory. The assessments further included standardized instruments to measure symptoms of depression, anxiety, eating disorders, alcohol use, and suicidal ideations.
RESULTS: Any self-harm was reported by 24.6% before and by 25.0% after OS. No differences in the number of self-harm behaviors or prevalence of any self-harm before and after OS were found. Overall, 11.4% experienced self-harm behaviors at both times. A subset showed self-harm behaviors only before (13.2%) OS and another subset only after OS (13.6%). These two groups were about the same size. Self-harm behaviors showed strong associations with psychopathology after OS, especially with depression and suicidal ideation.
CONCLUSIONS: No increase in self-harm behaviors after OS emerged. Still, a subgroup showed self-harm behaviors after OS closely linked to further psychopathology. This mirrors the need to implement screening for self-harm before and after OS into OS care. Further studies with longer follow up periods are needed to extend these findings.

摘要：
目标：先前关于肥胖手术（OS）的研究表明，患者不仅会减轻体重，而且还会改善某些心理健康结果（例如，抑郁症)。然而,操作系统后，自我伤害行为可能会增加。关于自我伤害，文献主要限于使用医院或急诊室图表数据的研究。这项纵向研究检查了OS前后的自我报告的自我伤害行为和潜在的精神病理学相关性。
方法：手术前患者（N=220）在OS前和OS后大约六个月填写了一组问卷。使用自我伤害量表捕获了自我伤害行为。评估还包括测量抑郁症状的标准化仪器，焦虑,饮食失调,酒精使用,和自杀的想法。
结果：在OS之前和之后的25.0％报告了任何自我伤害。OS前后自我伤害行为的数量或任何自我伤害的患病率均未发现差异。总的来说,11.4%的人在这两个时期都经历过自我伤害行为。一个子集仅在OS之前（13.2％）显示自我伤害行为，另一个子集仅在OS之后（13.6％）。这两组的大小大致相同。OS后，自我伤害行为与精神病理学表现出强烈的关联，尤其是抑郁和自杀意念.
结论：OS出现后，自我伤害行为没有增加。尽管如此，一个亚组显示OS后的自我伤害行为与进一步的精神病理学密切相关。这反映了在OS护理之前和之后实施自我伤害筛查的必要性。需要更长的随访时间的进一步研究来延长这些发现。
